    -device virtio-blk-pci,id=image1,drive=drive_image1,bootindex=0,bus=pci.0,addr=03 \
    -drive id=drive_image2,if=none,cache=none,format=qcow2,file=gluster://bootp-73-131-242.rhts.eng.pek2.redhat.com/gv0/stg1.qcow2 \
    -device virtio-blk-pci,id=image2,drive=drive_image2,bus=pci.0,addr=06 \
    -drive id=drive_image3,if=none,cache=none,format=qcow2,file=gluster://bootp-73-131-242.rhts.eng.pek2.redhat.com/gv0/stg2.qcow2 \
